BRANDON — Expansion plans for Brandon Regional Hospital are expected to lead to 146 full-time construction jobs and $60 million in direct economic impact through the end of 2016.

The hospital is expanding to meet increasing patient needs in Hillsborough County, which experienced a population increase of 5.1 percent between 2010 and 2013, according to the hospital. Since Brandon Regional opened its Plant City emergency room in October 2012, that facility has served more than 25,000 patients.

Among the slated projects:

• Build-out of the hospital’s A Tower Third Floor. Beginning in May, the hospital is slated to build out the tower’s shell space, adding 30 progressive care rooms and 10 intensive care rooms, for a total of 25,300 additional square feet.

• Parking garage. Construction on a 325-car expansion for the north garage is expected to start in August and be complete in December.

• Emergency department. With construction slated to begin in November 2014, the hospital will add a 72-bed, 84,510-square-foot emergency room with two additional 64-slice CT machines, a dedicated pediatric emergency department entrance, an EMS entrance with an elevated helipad and free valet parking.

When the new emergency department is completed, the old one will close, said Patricia Montgomery, spokeswoman for the hospital.

“As Hillsborough County continues to attract new residents, we’re committed to serving the growing needs of our community and creating jobs in the process,” Brandon Regional Chief Executive Officer Bland Eng said in a statement. “We look forward to expanding our capacity to provide quality, compassionate care to patients in our area.”
